Postoperative paresis of the intestine

Japanese: 術後腸管麻痺 - じゅつごちょうかんまひ（英語表記）postoperative paresis of the intestine

A condition in which intestinal motility is weakened or stops after abdominal surgery. This is particularly noticeable in surgeries in which intraperitoneal organs are directly manipulated. Intestinal paralysis may be caused by the effects of drugs used in general anesthesia or spinal anesthesia, but it is thought to be mainly due to mechanical stimulation of the intestines during abdominal surgery (traction, compression, cutting, suturing, etc.) that damages the nerve tissue in the intestinal wall related to intestinal motility. Excessive changes in humidity, such as drying or wetting of the intestinal wall, can also cause damage to the nerve tissue.

開腹手術の後に腸管の運動が減弱ないしは停止する状態。とくに腹腔内臓器に直接手が加えられる手術のときに著しい。腸管麻痺の原因は，全身麻酔や腰椎麻酔に用いた薬剤の影響である場合もあるが，主として開腹時の腸への直接の手術操作が機械的刺激(腸管の牽引，圧迫，切断，縫合など)となって腸管運動に関係する腸管壁の神経組織を障害するためと考えられている。また腸管壁の乾燥や湿潤など，湿度の過度の変化も神経組織の障害の原因となる。
